Although Everton's strikers have failed to make an impact this season and the Toffees have lost Australias Tim Cahill to the Asia Cup next month boss David Moyes is willing to listen to offers for a player who became the Premier Leagues youngest-ever scorer, against Palace in April 2005.

Vaughan has made 59 appearances for Everton, but only 11 of those have been starts and his progress has been slowed by serious knee and shoulder injuries.

But Vaughan's arrival could put serious question marks against the future of Jay Bothroyd, who is out of contract in the summer and eligible to talk to other clubs in January.

Now an England international, Bothroyd is sure to be targeted by other clubs in the transfer window.

But Jones knows he must strengthen with Cardiff having picked up only eight points from the last 27 on offer.

Though still holding second spot, Swansea and Leeds have drawn level on 40 points and the chasing pack have moved closer.

But Cardiff's billionaire backer Vincent Tan is expected to back Jones with cash in January and Vaughan is likely to be the first new face during a busy month.

Vaughan will hope to make his City debut against Leeds on Tuesday.

Cardiff have also been linked with a loan move for Manchester United youngster Federico Macheda.
